COMBINED CHURN AND BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 638,234, dated December 5, 1899. Application filed October 23,1896. Serial No. 609,779. (No model.)

To all whom it may concern:

Be it known that I, FRANK E. GILMORE, a citizen of the United States, residing in the county of Warren, State of Illinois, have invented certain new and useful Improvements in a Combined Churn and Butter-Worker,of which the following is a specification, which will enable others skilled in the art to which it belongs to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Prior to my invention, so far as known to me, in all combined churns and butter-workers in which the butter-working roller or rollers have been mounted within a revoluble cylinder near to the periphery of said cylinder and parallel with the axis of said cylinder said roller or rollers have been provided with shafts which projected through a head of the cylinder, which shafts served to carry the roller or rollers and were geared with driving mechanism for rotating the rollers. With roller-shafts thus projecting through the cylinder-head between its axis and periphery it was absolutely necessary to have loose cylinder-heads or heads formed in parts, such as shown and described in the Owens patent, No. 511,275, of December 19, 1893, in order to permit of rotating the cylinder, while the roller or rollers would not be revolved or carried around in an orbital path, but remain in stationary positions.

The leading object of my invention has been to solve the problem of providing a combined churn and butter-worker of the type referred to above and in which the churncylinder would have heads fixed thereto, and thus dispense with the loose heads or twopart heads, with their evident objectionable features.

To the end of carrying out the aforesaid object of my invention it consists in its main feature in a churn drum or cylinder having heads fixed thereto, which heads are each formed of an undivided part or part not separated into parts movable with respect to each other, and stub-axles, one of which projects through each of said heads and together form bearings on which the drum or cylinder is rotated,while the stub-axles are fixed,said stub- 3 of Fig. 2.

axles within said drum or cylinder carrying radial arms, on the outer ends of which are mounted a butter-working roller or rollers parallel with the axis of the cylinder and a short distance from the inner periphery thereof, as hereinafter fully described.

The invention further consists in constructions and combinations hereinafter described, and the different features of the invention are made the subject-matter of claims hereto appended.

In the annexed drawings, Figure 1 is aplan of my improved combined churn and butterworker. Fig. 2 is a transverse sectional elevation thereof on line 2 2 of Figs. 1 and 3. Fig. 3 is a horizontal sectional plan on line 3 Fig. 4 is a sectional elevation taken on line 4 4 of Fig. 3. Fig. 5 shows a detail of locking device for holding shaft.

The cylindrical vessel A has an opening in its side for putting in cream, taking out butter, &c., which is closed by a suitable lid B, preferably of the kind shown in the drawings. When the clamp-handle b, pivoted on the lid 13, is pressed down, its cam-flanges b clamp upon the levers or arms b pivoted on the body of the vessel, and thus the lid 13 is tightly fastened. The vessel A is provided with inwardly-projecting wings Ct, three or four in number,which act as dashers in churning. One of the heads (J of the cylinder A has the hub c fixed thereto at its center, and the short shaft or stub-axle D, which is releasably fixed to the frame E, passes through said hub and forms one of the bearings on which the cylinder A revolves. The other head F of the cylinder A has the hub f fixed thereto at its center, and the short shaft or stub-axle D, which is also releasably fixed to the frame E, passes through said hub and forms the other bearing on which the cylinder A revolves. The shafts D and G, which project into the cylinder A, have fixed to their inner ends, respectively, the radius-arms d and g. The arms cl and g are inside of the cylinder A and are held in horizontal positions by the shafts D and G when said shafts are fixed in position, as hereinafter described. The arms (1 and 9 have confronting short stub-axles d and g, respectively, on which a roller H is journaled. The roller H carries a pinion h at one of its ends, which meshes with a pinion a that is fixed to one of the cylinder-heads. The roller H has a rib or ledge h to cut the butter in working it. The roller H may be shifted longitudinally on its stubaxles cl and g, so as to throw it in or out of gear with the gear 04 and is secured in gear by the button 61 pivoted on the arm d, being turned as shown in Fig. 3. The roller II is secured out of gear by throwing back button 01 shifting the roller to the right, and then throwing the button g pivoted to the arm 9, into position.

When desired, for the purpose of cleaning, &c., the roller H may be taken out of the vessel by first moving the locking device 9 which fits on the squared end of the shaft G and locks and fixes said shaft to the frame F. to prevent its rotation until so removed, when it allows the shaft G to revolve in the journal-box e on the frame E. The shaft G, revolving while the other main shaft D remains stationary, releases the roller H at one end or the other from the stub-axles d or g. The locking device d which is constructed as the device g maybe withdrawn from the squared end of the other shaft D, and the roller may be released in this way.

The head 0 has a gear 0 into which mesh the teeth of the cog-wheel j, carried by the shaft J. This is secured in gear bythe button j as shown in Fig. 3. The buttonj may be thrown back and the shaft J shifted to'the right, which brings the cog-wheel j out of gear and brings the cog-wheel j into gear with the cog-wheel L on the hub c, which gear is secured by throwing the button 6 into position. Power is applied to the shaft J in any suitable manner, as by the pulley J.

This machine is used as a churn in the following manner: The roller H is thrown out of gear with the pinion a The cog-wheel j is thrown in gear with the cog-wheel L. Power is then applied to the shaft J, as by the pulley 3' rotating the vessel A in the direction shown by the arrow X in Fig. 2. The wings a strike the cream contained in the vessel A, thus churning it.

This machine is transformed into a butterworker in the following manner: The roller H is thrown in gear with the pinion a The shaft J is shifted to the left, throwing the cog-wheel into gear with the gear a The shaft J being then rotated in the same direction as in churning will rotate the vessel A in the direction of the arrow Z in Fig. 2. The butter is thus compressed again and again between the roller H and the side of the vessel nearest thereto. Experience has shown that buttercannot be worked effectually between such rollers and the inner side of the churn-cylinder without the roller is given positive rotations at substantially the same rate of speed at its periphery as has the adjacent inner side of the cylinder, whereby the butter will be compressed by direct pressure between the cylinder and the roller and not by any sliding action between the coacting parts and on the butter. The butter itself cannot be depended upon for rotating the roller, as it will accumulate at one side of and between the roller and cylinder, if said parts are located at but a short distance apart, and when it does pass through between them will be damaged by the indirect pressure it reoeives by sliding action of the parts on the thin sheet of butter, and if the roller is located farther from the cylinder the butter will not be thoroughly worked, as the sheet thereof is too thick for proper working. I have overcome these difficulties by giving positive rotary motion to the roller through the instrumentality of a pinion or gear wheel fixed to the inner side of one of the cylinderheads and with which a pinion on the roller can be moved into gear. Thus I effect a gear connection between the roller and the cylinder without any holes for the roller-journals extending through the cylinder head or heads and which holes are indispensable in churns in which two-part cylinder head or heads are used and a gear with the roller is on the outer side of the cylinder-head.

Of course I do not confine myself to the mechanism hereinbefore described any more than is pointed out in the claims.
